The Ultimate LinkedIn Image Size Guide: Dimensions, Specs, and Cheat Sheet

First impressions on LinkedIn happen in milliseconds. When a professional lands on your profile or scrolls through their feed, visuals are processed far faster than text. Yet, nothing undermines professional credibility quite like a pixelated header banner, a cropped-off headshot, or a feed post awkwardly warped by random letterboxing.

Because LinkedIn dynamically adjusts layouts across desktop monitors, tablets, and mobile phones, hitting the correct pixel dimensions is non-negotiable.

This comprehensive guide breaks down every exact image size, format, and optimization tip you need for your personal profile, company page, and content strategy.

1. Personal Profile Image Dimensions

Your personal profile is your digital handshake. Keeping these graphics sharp and properly proportioned establishes instant trust.

| Asset Type | Recommended Dimensions | Aspect Ratio | Max File Size | Format |
| :— | :— | :— | :— | :— |
| Profile Photo | 400 × 400 px (minimum) | 1:1 (Square) | 8 MB | JPEG, PNG, GIF |
| Background Banner | 1584 × 396 px | 4:1 | 8 MB | JPEG, PNG, GIF |

• Profile Photo Tips: LinkedIn crops your profile photo into a circle. Ensure your face is centered, and keep crucial details well away from the corners where they risk being clipped.
• Background Banner Tips: This wide banner is prime real estate for personal branding, a tagline, or a subtle call-to-action. Keep in mind that your profile photo overlaps the bottom-left corner of the banner on desktop (and shifts near the center on mobile), so keep your core text and logos on the right side.

2. Company Page Image Dimensions

Building a brand presence requires specific asset sizes that differ slightly from personal profiles.

| Asset Type | Recommended Dimensions | Aspect Ratio | Max File Size | Format |
| :— | :— | :— | :— | :— |
| Company Logo | 300 × 300 px (or 400 × 400) | 1:1 | 4 MB | PNG (Transparent) or JPEG |
| Company Cover Banner | 1128 × 191 px | ~5.9:1 | 4 MB | JPEG, PNG |
| Life Tab Hero Image | 1128 × 376 px | 3:1 | — | JPEG, PNG |

• Logo Tips: Use a clean PNG with a transparent background if possible. Because company logos appear tiny next to comment threads and search results, opt for a high-contrast, simplified version of your logo rather than a complex icon.
• Cover Banner Tips: Unlike personal banners (which are 4:1), company banners are much wider and shorter (1128 × 191 px). Always design specifically for these dimensions rather than reusing your personal asset.

3. Feed Post Image Sizes (The Engagement Drivers)

Your feed content is where image dimensions matter most for stopping the scroll. LinkedIn supports three primary image layouts for single-image posts:

A. Square Posts (The Reliable Default)

• Dimensions: 1080 × 1080 px
• Aspect Ratio: 1:1
• Best For: Quotes, product announcements, infographics, and general cross-platform sharing. They display consistently across all viewports without unexpected cropping.

B. Portrait Posts (The Mobile-First Power Play)

• Dimensions: 1080 × 1350 px
• Aspect Ratio: 4:5
• Best For: Infographics, step-by-step breakdowns, and deep-dive visuals. Because over 60% of LinkedIn usage is mobile, portrait posts consume maximum vertical screen space, pushing competing posts out of view. Note: Avoid going taller than 4:5, or LinkedIn will aggressively crop the top and bottom.

C. Landscape / Link Preview Posts

• Dimensions: 1200 × 627 px
• Aspect Ratio: 1.91:1
• Best For: Sharing external website links or landscape photography. When sharing URLs, LinkedIn pulls this exact dimension for its Open Graph preview card—getting it wrong results in awkward cropping or white letterboxing.

4. Carousels, Documents, and Articles

• Carousel / Document Posts: Uploaded as PDF files (up to 100 MB and 300 pages). The ideal slide dimension is 1080 × 1080 px (Square) or 1080 × 1500 px / 1080 × 1350 px (Portrait). Carousels regularly yield high engagement, making clean typography and legible font sizes (minimum 24px equivalent) essential.
• LinkedIn Articles & Newsletters: Feature cover images should be designed at 1920 × 1080 px (16:9 ratio) to ensure crisp rendering at the top of long-form thought-leadership pieces.
• Video Thumbnails: Upload custom thumbnails at 1920 × 1080 px (16:9) to match standard HD video formatting.

Golden Rules for Perfect LinkedIn Visuals

1. Match Format to Content: Use PNG for graphics, charts, and text-heavy assets to keep lines razor-sharp. Use JPEG for photographs to keep file sizes low without sacrificing visual fidelity.
2. Respect the Safe Zones: Never place critical text or logos right against the margins. Different screen sizes and mobile operating systems can trim edge pixels.
3. Avoid Upscaling Small Images: Always design at or above the recommended pixel dimensions. If you upload a small image, LinkedIn will stretch it, resulting in heavy pixelation and blurriness.
4. Preview Before Publishing: Always use LinkedIn’s draft or preview environment to check how your image looks on a mobile phone before hitting publish.
